GSLV-III in its experimental mission will haul a crew capsule weighing 3.5 tonnes, devoid of astronauts in the first week of July, and it will return to earth via a parachute.

It is a replica of the crew module that will be put into orbit in its real mission of sending humans to space which ISRO calls The Human Space Flight program (HFS).

The rocket will do a passive sub-orbital flight, that is, reach an altitude of less than 100 km, its upper cryogenic stage will not fire, the cryogenic stage would carry liquid nitrogen, which would be inert.
